Effects on P-Glycoprotein Expression after Blood-Brain Barrier Disruption Using Focused Ultrasound and Microbubbles

PLoS ONE, 2017
Many blood-borne substances attempting to pass through the luminal membrane of brain endothelial cells are acted upon by a variety of metabolizing enzymes or are actively expelled back into the capillary lumen by embedded efflux transporters, such as ...

Enzymatic microbubble robots

Nature Nanotechnology
The development of micro- and nanorobots has amplified the demand for intelligent multifunctional machines in biomedical applications, but most microrobotic systems struggle to achieve the attributes needed for those applications. Here we introduce enzymatic microbubble robots that exhibit steerable motion, enhanced biodegradability, high in vivo ...

Plasmonic microbubbles: nucleation, growth and collapse [PDF]

, 2020
Noble metal nanoparticles immersed in a liquid and irradiated by resonant light can rapidly heat up to high temperatures, due to their peculiar absorption ability, and transfer the heat to the surrounding liquid, leading to the formation of bubbles, which have broad application potential in many plasmonic-enhanced processes.
